1 Claim. (Cl. 229-52 container of the character stated which may be usedre peatedly.

Another object of this invention is to provide a shipping container ofthe character stated which may be constructed from a single cut andscored blank of corrugated board or the like and which utilizespractically the whole area of a rectangular sheet, thus minimizingmaterial waste.

Another object of this invention is to provide a shipping container ofthe character stated which has greatly reinforced end walls to withstandthe stresses imposed thereon during handling and storing.

Another object of this invention is to provide a shipping container ofthe character stated which includes top closure flaps integral with theside walls and provided with side and end flanges adapted to enterreceiving grooves formed by the upper portions of the end walls.

Another object of this invention is to provide a container of thecharacter stated which includes a bottom, side walls, multi-ply endwalls provided with handholes and flange-receiving grooves, and a pairof top closure flaps carried by said side walls and provided with sideand end flanges adapted to enter the receiving grooves formed by the endwalls.

Another object of this invention is to provide a container of thecharacter stated which can be shipped and stored in a flat, knocked-downform and then simply and quickly erected when needed, thus conservingvaluable space prior to actual uselof the container.

With these and oth r objects in .view, the nature of which will be moreapparent, the invention will be more fully understood by reference tothe drawings, the accompanying detailed description, and the appendedclaim.

In the drawings,

Fig. 1 is a perspective view of an erected container constructed inaccordance with this invention;

Fig. 2 is an enlarged, vertical section of one end taken along line 22of Fig. 1;

Fig. 3 is a plan view of a blank from which the container may be formed;and

Fig. 4 is an enlarged horizontal section taken along line 44 of Fig. 1.

Referring to the drawings in detail, the invention as illustrated isembodied in a shipping container so constructed and proportioned as tobe particularly suitable for use as a container for shipping bottledgoods.

The container is formed from a single cut blank of corrugated board orthe like, generally designated at 5, which includes a bottom 6 and sidewalls 7a, 7b. The bottom carries a pair of outer end panels 8, 8- whichare provided with cut-out handholes 9. The side wall 7a carries at eachend an inner end panel 10 provided with a cut-out handhole 11. and aninner end reinforcing panel 12 extending from one side of the panel 10.The panel 12 is provided with a cutout handhole 13 and tapers generallyoutwardly. The side wall 71) carries at each end a central end panel 14provided with a cut-out handhole 15 and an outwardly taperingreinforcing panel 2,102,155 Patented Feb. 15, 1955 2 a 16 similar to thepanel 12 and which is provided with a hand-hole flap 17. Score lines '18separating the panels 14 and 16 are preferably reverse scored ascompared to the remaining score lines of the blank. Each of the sidewalls 7a and 7b carries a top closure flap 19 provided at each end withrounded end flanges 20 and a long narrow side flange 21. Said closureflapsare also provided at each end with notch formations, indicated at22, between the side and end flanges thereof. Cut out drainage holes 23may be provided and are so spaced on the blank that they will be indiagonally placed bottom corners when the container is erected.

-By referring to Fig. 1 of the drawings it will be observed that acarton constructed in accordance with this invention when erected hasthe bottom 6, side walls 7a, 7b, five-ply end walls formed from thepanels 8, 10, 12, 14, 16, and top closure flaps 19 so arranged as todefine a generally rectangular body. The five-ply endvwalls may bestapled as at 24, glued or fastened by other means to retain the shapeof the carton. The several handholes are so placed on the blank thatthey are in alignment when the box is erected and the handhole flaps 17of the panels 16 can be folded in through the combined aligned handholesand then folded upwardly as shown in big. 3.

lt should be noted that the end walls are termed to provide in theerected container a receiving groove 25 adapted to receive the roundedend flanges 20 of the top closure flaps 19. The outer end panel 6 isfirst folded into position, then the central end panel 14 is broughtinto uxtaposition with the internal surface of the outer panel 8. Nowthe outer end reinforcing, panel 16 is folded outwardly over the panel25 and down into juxtaposition With the external surrace of the panel 8so that upon fastening the three panels 8, 14, 16 rorm a unitary wallportion. The inner end panel 10 is then brought into an aligned positioninside the above formed unit and the inner end lCiIlIOl'Clllg panel 12is folded inwardly and downwardly into JUXIEIPOSlIlOD with inner panel10 so that upon rastening the two panels 10, 12 form another unitarywall portion. As will be noted from Fig. l, the staples 24 holding theend walls together are not placed higher than a short distance below thehandholes in the central area of the end walls, although it is possibleto place them much higher at the external edges of the end walls. .By soplacing the staples the inner wall unit composed of panels 10, 12 may bepushed slightly inward while the outer wall unit composed of panels 8,14, 16 remains in position, thus forming the receiving groove 25, asshown 111 rig. 3, which is adapted to receive the end flanges 20 of thetop closure naps 19. it should be noted that the manner of forming theend walls is such that the receiving groove 25 is termed withoutrequiring the use of additional material. The notches 22 between theside flanges and end flanges at the respeo tive outer corners of the topclosure flaps allow the closures to pass over and fit snugly about theinner end unit composed of panels 10, 12.

Many efforts have heretofore been made to provide shipping cartonsadaptable for the packaging of bottled goods in which the container isstrong enough to withstand wear and tear of repeated usage and toprovide an easily opened closure that will not tend to open from thestress of handling. Most of the stress from handling these containers ison the end walls and the stresses from storage on the upper edges.Attemptsto provide slotted and reinforced ends have invariably compelledthe use of additional blanks which requires more labor and material. Thecontainer herein described has added strength at the upper side edgesdue to the closure flaps being integral with the side walls. The endwalls are five-ply thick so can withstand great stress and make a strongupper edge. In addition thereto the end walls are provided withreceiving grooves adapted to receive the end flanges of the top closure,thus assuring a more stable closed package unit and also helping tomaintain the shape of the container while being handled. I

It is, of course, to be understood that various details of arrangementsand proportions of parts may be modified within the scope of theappended claim.
